Question

The system of equations y= 1/4x-1 and y= -1/2x-1/4 is shown on the graph below.

What is a reasonable estimate for the solution?
A. (1, -3/4)
B. (-3/4, 1)
C. (-1, 3/4)
D. (3/4, -1)

Answer 1

1,-3/4

Explanation:

Answer 2

A:(1,-3/4)

Explanation:

Use substitution to solve the system

y= 1/4x-1

y= -1/2x-1/4

1/4x-1 = -1/2x-1/4, Solve for x

3/4x= 3/4, x = 1, Next solve for y by plugging the x-value into either equation.

y=1/4(1)-1

y=-3/4
